The Use of Oral Amino-Bisphosphonates and Coronavirus Disease 2019 (COVID-19) Outcomes

The determinants of the susceptibility to severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection and severe coronavirus disease 2019 (COVID-19) manifestations are yet not fully understood. Amino-bisphosphonates (N-BPs) have anti-inflammatory properties and have been shown to reduce the incidence of lower respiratory infections, cardiovascular events, and cancer. We conducted a population-based retrospective observational cohort study with the primary objective of determining if oral N-BPs treatment can play a role in the susceptibility to development of severe COVID-19. Administrative International Classification of Diseases, Ninth Revision, Clinical ModificationI (ICD-9-CM) and anatomical-therapeutic chemical (ATC) code data, representative of Italian population (9% sample of the overall population), were analyzed. Oral N-BPs (mainly alendronate and risedronate) were included in the analysis, zoledronic acid was excluded because of the low number of patients at risk. Incidence of COVID-19 hospitalization was 12.32 (95% confidence interval [CI], 9.61–15.04) and 11.55 (95% CI, 8.91–14.20), of intensive care unit (ICU) utilization because of COVID-19 was 1.25 (95% CI, 0.38–2.11) and 1.42 (95% CI, 0.49–2.36), and of all-cause death was 4.06 (95% CI, 2.50–5.61) and 3.96 (95% CI, 2.41–5.51) for oral N-BPs users and nonusers, respectively. Sensitivity analyses that excluded patients with prevalent vertebral or hip fragility fractures and without concomitant glucocorticoid treatment yielded similar results. In conclusion, we found that the incidence of COVID-19 hospitalization, intensive care unit (ICU) utilization, and COVID-19 potentially related mortality were similar in N-BPs–treated and nontreated subjects. Similar results were found in N-BPs versus other anti-osteoporotic drugs. We provide real-life data on the safety of oral N-BPs in terms of severe COVID-19 risk on a population-based cohort. Our results do not support the hypothesis that oral N-BPs can prevent COVID-19 infection and/or severe COVID-19; however, they do not seem to increase the risk. © 2021 The Authors.

Aponeurotic-Cutaneous Tract Exeresis in Patients With Persistent Lymphorrhea After Kidney Transplantation: A Valid Approach in a Day Surgery Setting

BackgroundLymphatic disorders (LDs) are the most common minor complications after kidney transplantation (KT), with an incidence rate between 0.6% and 33.9%, which appears to be related to both surgical and medical factors. LDs mostly resolve spontaneously, but occasionally a surgical approach may be required.Materials and MethodsWe report our experience with 7 KT recipients who developed persistent lymphorrhea (>150 mL/24 h) between October 2017 and March 2019. All cases were treated as outpatients with parietal fistulectomy (PF). The fibrotic aponeurotic-cutaneous tract was thoroughly excised, and the residual aponeurotic defect was closed by watertight suturing. Serial abdominal ultrasounds (US) were carried out after the procedure.ResultsA small perirenal graft lymphocele of <2 cm was detected by US in all patients after 48 to 72 hours, without any evidence of either vascular or ureteral compression. During the subsequent scheduled US follow-up, lymphoceles did not increase in size, and additional interventions were not needed. Neither superficial nor deep surgical-site infections were recorded in such patients.ConclusionsPF was found to be a safe and effective minimally invasive approach for persistent lymphorrhea after KT. It could be easily performed with local anesthesia in a day surgery setting and did not require patient hospitalization.     

The combination cytology/epichek test in non muscle invasive bladder carcinoma follow-up: Effective tool or useless expence?

ObjectiveTo identify in which cases after cytological diagnosis, the Bladder EpiCheck test could represent an effective tool in non-muscle invasive bladder carcinoma or an useless expence.Materials and methods375 patients diagnosed with non-muscle invasive bladder cancer, 269 with high grade urothelial carcinoma and 106 with carcinoma in situ, were treated and followed for 1 year. The treatment was an intravesical instillation of Bacillus Calmette-Guerin in 305 patients and Mitomycin-C in 70 patients.During the follow-up patients were evaluated by voided urine cytology and white-light cystoscopy, according to the European Association of Urology Guidelines. Bladder EpiCheck test was performed together with cytology in all cases.ResultsAnalyzing Bladder Epicheck results for each category defined by the Paris System for Reporting Urinary Cytology, we found that the Episcore >60 correlates with histological diagnosis of high grade urothelial carcinoma (HGUC) in atypical urothelial cells and Suspicious for High Grade Urothelial Carcinoma (P = 0.0002 Odds Ratio 0.05926 95% Confidence Interval from 0.01127 to 0.3116 and P = 0.0009 Odds Ratio 0.0315595% Confidence Interval from 0.001683 to 0.5914, Fisher's exact test, respectively), while in Negative for high grade urothelial carcinoma and HGUC patients Episcore is not helpful to identify cases with histological diagnosis of HGUC (P = 0.101 and P = 0.58 Fisher's exact test, respectively). Considering an Episcore ≥ 90 in the HGUC cytological group, this seems not to be correlated with a histological diagnosis of HGUC (P = 0.090 Fisher's exact test).ConclusionsCytology and Bladder EpiCheck test in combination may have the potential to reduce cystoscopies in the follow-up of non-muscle invasive bladder cancer only for cytological diagnoses of atypical urothelial cells and Suspicious for High Grade Urothelial Carcinoma . Moreover, in patients with a cytological diagnosis of Negative for high grade urothelial carcinoma or HGUC, cytology alone seems to be safe and cost-effective.     

Range of motion of foot joints following total ankle replacement and subtalar fusion

BackgroundIn severe cases of ankle and subtalar arthritis, arthrodesis of the subtalar joint is performed in combination with ankle arthroplasty. In these special cases gait analysis reveals real motion at the replaced tibiotalar joint.MethodsTwenty-three patients affected by ankle and subtalar arthritis, treated either with a 3-component or a 2-component prosthesis in combination with subtalar arthrodesis, were clinically evaluated preoperatively and at a minimum of 1-year follow-up. Gait analysis was performed postoperatively using a multi-segment foot protocol. Foot kinematics were compared to corresponding data from a healthy control group.ResultsClinical scores significantly improved from preoperative to follow-up. The clinically measured passive ankle dorsiflexion/plantarflexion significantly improved at the follow-up. Patients’ normalized walking speed and stride length were significantly lower than those in control. With exception of the ankle frontal-plane motion, sagittal-plane mobility of foot joints was about 50% than that in healthy joints.ConclusionsImprovement in clinical scores was found for both prostheses. Normal spatio-temporal parameters were not restored. In these patients, fusion of the subtalar joint appeared to be compensated by larger frontal-plane motion at the tibiotalar joint.Level of evidenceLevel III- retrospective comparative study.The study was approved by the local Ethics Committee as protocol MAT (protocol registration at clinicaltrials.gov NCT03356951).     

Developmental dysplasia of the hip screening during the lockdown for COVID-19: experience from Northern Italy

PurposeDevelopmental dysplasia of the hip (DDH) ultrasound screening (USS), which is usually performed in Italy as an outpatient, was halted for an indefinite period in most centres during lockdown. The aim of this study was to analyze the effect of COVID-19 on DDH-USS, in two paediatric orthopaedic centres in one of the most critical areas of the western World.MethodsAn academic teaching hospital and paediatric trauma centre (T) and a University hospital and DDH referral centre (H), classified as national COVID-19 hubs, were involved. Graf’s method was applied in both centres. In T, paediatricians directly referred only patients with delayed DDH-USS or suspicious unstable hips; in H, paediatricians or parents could directly refer to the screening service.ResultsThe mean age of the 95 patients (190 hips) who were referred for DDH-USS in T, was 3.85 months (0.1 to 7.4); 175 were type I, nine were type IIa (+ and -), five type D and one type IV. In H, the screened patients in 2020 were only 78% of the same period in 2019. A total of 28 patients with 32 hips (8 IIb, 5 IIc, 8 D, 11 III) had late diagnosis at a mean age of 114 days (96 to 146). In the same period in 2019 only eight patients with 11 hips (8 IIb, 1 D, 1 III, 1 IV) at a mean age of 142 days (92 to 305) had late diagnosis.ConclusionDDH-USS was the only screening in newborns which halted during lockdown. Few centres, which still performed diagnosis and treatment, were overloaded causing a delay in DDH management.Level of evidenceIV.     

Technical basis for magnetic resonance images

The spin-echo procedure is the basic technique in a magnetic resonance (MR) study (the magnetization vector is flipped by 90° onto the ortogonal plane to the main magnetic field). Very soon after the MR procedure was developed, it was pointed out how important it is to achieve the needed contrast with shorter repetition times (TRs) to reduce the imaging time. Recently, fast imaging techniques have been introduced (partial flip angles, short TRs, and the lack of 180° radiofrequency pulses to refocus the spins are their main characteristics; the spins are refocused by the application of a gradient reversal technique). These techniques are particularly needed in pediatric neuroradiology, where the examination time must be as short as possible. At present, partial flip-angle techniques are almost completely replacing the conventional spin-echo procedure, but the variations in flip angle could result in a change in contrast. For these reasons, conventional spin-echo techniques may still be useful in a routine MR study.Presented at the 11th Meeting of the European Society for Paediatric Neurosurgery, Naples 1988
